The following document outlines the requirements of the laboratory space into which your new LS Spectrometer will be installed. In order to ensure optimum performance and timely installation we ask you to kindly review the contents of this document and sign and return this form to acknowledge your comprehension of these important criteria. If you have any questions concerning these requirements, please do not hesitate to contact us.

Please provide to us an overview picture of the lab where the instrument will be installed and where the optical table will be positioned if it is not already in place. We would like to help ensure that the space is adequate for installation and operation of your new instrument. The optical table must be metric and have at least the dimensions 110x60 cm. We suggest dimensions of 90x160 cm with a thickness of 12cm. There must be space all around the table such that the service engineer can easily access. If the setup should be accommodated on a table with other equipement a space of 120x170 cm should be available.

2. 电源插座

光学平台附近至少需要5个的欧式三孔电源插孔，我们更希望提供一个多头插线板最好。

A sufficient number of power outlets must be available near the optical table. We have installed 5-pole Euro plugs (Schuko) on all AC power connections and will deliver a multi-outlet power strip with adapter to the Type D connection. Spare outlets are of course always welcome.

The instrument computer must have access to the internet. This is necessary for setup, software updates and potential troubleshooting. It would be really useful if an internet connection close to the optical table could also be arranged for the LS technician’s laptop during the service.

4. 环境光线要求

放置仪器的房间光线要求可控制变暗。鉴于激光操作安全原因，在安装调节过程中，此房间应限制出入。

It is necessary that the room can be completely or nearly darkened. It’s important also that access to the area can be restricted during alignment procedures for the purposes of laser safety

The LS Spectrometer is a precision optical instrument and requires a climate controlled environment. The laboratory should be held at a temperature of 17-26°C and maintain a stability of ±3°C over any 8 hour period. Humidity must also be controlled and kept below 60% relative humidity. If measurements at temperatures below ambient temperature are to be made, specific attention to relative humidity should be given and operation at sample temperatures below the dew-point are only possible with purging of the outer index-matching vat surface with dry air or nitrogen. We would encourage you to take temperature and humidity measurements in your laboratory over a 24 hour period to verify the suitability of your chosen lab space for your new instrument.

我们不希望因为缺少上面提到的需要材料，安装空间而影响安装，否则再次安装我们会收取一定的费用。

Disclaimer

We must unfortunately stipulate that should we inhibited from reasonably proceeding with all phases of the setup procedure during the scheduled time due to major setbacks arising from a lack, on your behalf, of requested materials, adequate space, or sufficient permitted focused installation time, we would have to charge for an additional service visit if it is necessary.
